The Mexican government, likely without any fear that effective border control would force it to provide its own economy, sent a stern warning to President Bush about The Fence:
Mexico pleaded with President Bush on Monday to veto a Senate proposal to build a fence to keep illegal immigrants out, saying it could backfire by making the border less secure.
First of all, at this point I doubt that's possible.
Secondly, according to the Reuter's author - who apparently didn't think to ask - Mexico offered no evidence as to how a giant fence would actually hinder security. (Ed. - I looked up the word fence and found no evidence that its historically accepted effectiveness had been challenged by any credible study.)
Lastly, and in light of all that, does anyone else read it as a threat?
